Abstract
An elliptically polarized cavity backed wideband slot antenna with a planar log-periodic dipole is provided. Sufficiently large bandwidth is achieved with careful design of the dipole. Also, the antenna has constant E-field distribution and good impedance properties, and ensures a constant power ratio for vertical polarization and horizontal polarization over a broad frequency band.
